Electric Charge
Learning Objectives
- Understand the concept of electric charge and how it occurs through the movement of electrons between atoms.
- Explain how objects become positively or negatively charged through the transfer of electrons.
- Describe the attraction and repulsion forces experienced by objects due to electric charge.
- Identify real-world examples of static electricity and electric charge, such as clothing in a dryer and hair on a trampoline.
- Recognize the role of friction in causing the transfer of electrons and the resulting build-up of static electricity.
Introduction and Hook
Discuss real-world examples of static electricity, such as clothing sticking together in a dryer or hair standing on end after jumping on a trampoline.
Direct Instruction
Explain the movement of electrons and how objects become charged. Use diagrams to illustrate the process of electron transfer and the resulting positive or negative charge.
Introduce the video 'Electric Charge' to visually demonstrate the principles of attraction and repulsion between charged objects.
Guided Exploration
Engage students in a discussion about the role of friction in causing the transfer of electrons and the build-up of static electricity.
Watch the video 'Electrical Conductors and Insulators' to understand how different materials interact with electricity and the importance of conductors and insulators.
Hands-On Activity
Conduct a simple experiment using balloons and wool cloth to demonstrate static electricity. Have students observe and record their findings.
Use the 'Aluminum Can Race!' assessment to explore static electricity further. Students will use a balloon and cloth to move an aluminum can without touching it.
Independent Practice
Assign students to identify and list examples of static electricity in their homes or surroundings, such as socks sticking to clothes or a plastic comb attracting paper bits.
Check for Understanding
Use the 'Electric Charge – Comprehension' assessment to evaluate students' understanding of electron gain and loss, and the attraction and repulsion of charges.
Review and Reflection
Facilitate a class discussion to review key concepts learned about electric charge and static electricity. Encourage students to share their observations and findings from the hands-on activities.
Assessment and Extension
Administer the 'What Is Electricity?' assessment to test students' comprehension of basic electricity concepts and their practical applications.
Try the Quiz
Encourage students to explore further by watching the 'Electricity – Sources and Uses' video to understand the generation and application of electricity in daily life.
